Comment(by vbraun):
There is `sage.rings.pari_ring` which implements parents and elements. But
when Pari is used in the Sage library its usually directly via its C API.
Looking at Python's C API, it seems that `Py_AtExit()` is what we want: A
callback for a cleanup function that is run after Python is finalized. In
fact anything from `quit_sage()` that just finalizes a C library should
probably be moved there. See http://docs.python.org/c-api/sys.html
